Frequently asked questions
- How many surgeons perform Fem-Pop Artery Stent in Tennessee?
- 7 Tennessee providers billed Medicare for Fem-Pop Artery Stent (CPT 37226) in CY2024. CMS suppresses providers with 10 or fewer Medicare patients, so the true count is somewhat higher.
- Where does this data come from?
